Aviation enthusiasts Samantha Gill, 13 and her father Mike Gill, of Chino Hills, pose for a photo in front of a British Spit Fire WWII plane while parked at the Burbank Airport on Saturday, March 23, 2013. After two engine tests on a B-29 Superfortress bomber were done, it was determined that a mechanical malfunction would keep the World War II-era bomber grounded for the day.
